What running a company in Poland really costs in 2026 — the complete breakdown

The real cost of running a business in Poland in 2026 ranges from a few thousand złoty a year for a sole trader still inside the relief period, to several tens of thousands for an active limited company with full accounting and full ZUS. The difference does not come from one big line item but from the sum of a dozen smaller ones — contributions, taxes, accounting, and costs nobody mentions in the adverts. This guide sets out all the 2026 figures: ZUS contributions to the złoty, the health contribution by tax regime, taxes, fixed and hidden costs, and the point at which a limited company becomes cheaper than a sole trader.

If you are only just setting up, start with our guide to company registration; here we focus on what happens after registration — the cost of keeping a business running through its first three years.

In brief

• Minimum wage 2026: PLN 4 806 gross (a single threshold, no mid-year rise); forecast average wage: PLN 9 420
• Full ZUS (excluding health): PLN 1 926.76 per month (PLN 1 788.29 without the sickness contribution)
• Preferential ZUS: PLN 456.18 per month for 24 months; Relief for a start: zero social contributions for the first 6 months (the health contribution always applies)
• Health contribution 2026: a minimum of PLN 432.54 per month (tax scale and flat tax); the reform that would have cut it was vetoed — the existing rules stand
• CIT: 9% for small taxpayers (revenue up to PLN 8.517 million), 19% as standard; the VAT exemption threshold rose to PLN 240 000
• When a Sp. z o.o. beats a sole trader: usually above roughly PLN 200 000 of annual income, mainly thanks to 9% CIT and the absence of ZUS for board members of a multi-shareholder company

What a company’s cost is actually made of

Entrepreneurs usually ask for a single number — “how much does a company cost per month”. The honest answer is that it depends on five variables, each capable of moving the total by hundreds or thousands of złoty:

1. Legal form — sole trader or Sp. z o.o. (this determines ZUS and the method of taxation)
2. Tax regime — the scale, flat tax or lump sum (for a sole trader), or CIT / Estonian CIT (for a company)
3. Stage of activity — powerful ZUS reliefs apply during the first 30 months
4. Revenue level — it decides the health contribution, the right to 9% CIT and whether VAT exemption is worthwhile
5. Fixed costs — accounting, address, software — items that look minor but add up to thousands over a year

Let us take each one apart.

ZUS 2026 — the largest item, but not from day one

For a sole trader, ZUS is usually a heavier burden than income tax. The key news for anyone starting out: you pay significantly less for the first two and a half years, thanks to three consecutive reliefs.

Full ZUS (social contributions)

The assessment base is 60% of the forecast average wage, which in 2026 means PLN 5 652. Social contributions are calculated on that:

These are social contributions only — the health contribution is calculated separately (see below) and added to the amounts above.

Three reliefs that lower the start

• Relief for a start (months 1–6): exemption from all social contributions. You pay only the health contribution. Available for a first business or after a 60-month break.
• Preferential ZUS (months 7–30): the base is 30% of the minimum wage (PLN 1 441.80), so social contributions come to PLN 456.18 with the sickness contribution (PLN 420.86 without). For 24 months.
• Mały ZUS Plus (after the preferential period): for businesses with previous-year revenue up to PLN 120 000 — the contribution is calculated in proportion to income, within a band running from the preferential amount to the full one. Available for 36 months in any 60-month period.

The practical conclusion. A new sole trader pays only the health contribution to ZUS in the first half-year, and for the following two years a few hundred złoty a month instead of nearly two thousand. That changes the economics of the first three years and is worth planning deliberately.

Who ZUS does not apply to — and the single-shareholder trap

A board member of a multi-shareholder Sp. z o.o., appointed by resolution, is not subject to ZUS social contributions on that basis — one of the company’s main advantages over a sole trader at higher income levels. But there is a trap: the sole shareholder of a single-shareholder Sp. z o.o. is treated by ZUS as an entrepreneur and pays full ZUS and the health contribution just as in a sole trader business. The typical solution for one-person businesses is therefore to admit a second shareholder. (A remunerated board member serving on appointment may in turn be subject to the health contribution alone — this aspect is worth confirming with your accountant for your specific situation.)

The health contribution 2026 — the reform was vetoed, the old rules stand

This is the item most often described wrongly in 2025. Let us set out the facts: the act reducing entrepreneurs’ health contribution was vetoed by the President in May 2025 and did not enter into force. In 2026 the existing rules apply, with one change — the temporarily reduced minimum base (75% of the minimum wage) returned to 100%, so the minimum contribution rose.

The contribution depends on the tax regime (amounts in force from February 2026 to January 2027):

Under the scale the health contribution is not deductible; under the flat tax it can be deducted from the base up to an annual cap; under the lump sum above PLN 300 000, half is deductible. (In January 2026 a lower base from the 2025 contribution-year settlement still applied — the amounts above relate to the period February 2026 – January 2027.)

Taxes 2026 — CIT, PIT, lump sum, Estonian CIT

CIT (companies): 9% for “small taxpayers” whose revenue does not exceed the equivalent of EUR 2 million (around PLN 8 517 000 in 2026), and for companies in their first year; 19% above that. You must, however, bear in mind double taxation when profit is distributed: CIT at company level, then 19% dividend tax at shareholder level. The effective burden on distributed profit is therefore higher than the CIT rate alone.

Estonian CIT (lump-sum taxation of company income): it shifts the moment of taxation to the point of profit distribution. The rates are 10% (small taxpayer / start-up) and 20% (others), and the effective burden on a distribution can be lower than under the classic model. It does, however, require meeting conditions — shareholders may only be natural persons, the company may not hold shares in other entities, and it must maintain a minimum level of employment.

PIT (sole traders):

• Scale: 12% up to PLN 120 000 of income, 32% above; tax-free amount PLN 30 000 (unchanged — the increase to PLN 60 000 has been deferred).
• Flat tax: 19% regardless of income — worthwhile at higher income levels.
• Registered lump sum: the rate depends on the type of activity — for example 12% or 8.5% for some IT services, 8.5% for many services. The lump sum is charged on revenue (with no deduction for costs), so it pays off where costs are low.

VAT: the subjective exemption threshold rose in 2026 to PLN 240 000 (previously PLN 200 000). Note: some activities — advisory and legal services among them — are subject to VAT from the first złoty, regardless of turnover. We describe registration in detail in our guide to VAT registration with a virtual office.

Fixed costs — accounting, address, registration

Accounting is the second largest item after ZUS and the biggest difference between the forms:

A Sp. z o.o. must keep full accounting records from day one — an inherent, permanent cost that a sole trader avoids up to certain thresholds.

Registered address (virtual office). Real market prices in 2026 are lower than many entrepreneurs assume:

The “from PLN X” trap. Prices advertised as “from PLN 20–30” are almost always rates for prepayment of 12 or 24 months. On a month-to-month basis the same package usually costs 1.6–3 times more. Compare prices on the same billing basis.

A business bank account. In practice this item is often free. Several banks offer a business account with no fees and no conditions (Alior, Nest and Erste — formerly Santander — among them); most waive the fee on condition of a monthly ZUS transfer or minimum inflows, and charge around PLN 12–25 a month where the condition is not met. The real cost appears only with foreign transfers (SWIFT roughly PLN 25–75 per transfer) — SEPA is unconditionally free at only some banks.

Registration (one-off cost): under the S24 online procedure the court fee is lower than with a notarial deed; on top of that comes PCC of 0.5% on the share capital (less the court fee). (The Court and Business Gazette fee was abolished at the end of 2025.)

Hidden costs — the ones nobody mentions at the start

• The employer’s cost of an employee: on top of gross pay you must add around 20.5% in employer contributions (plus a minimum 1.5% for PPK). A post paying PLN 6 000 gross really costs the business over PLN 7 200.
• Double taxation in a company on profit distribution (CIT plus 19% on the dividend).
• Split payment and cash flow — the split payment mechanism can freeze funds in the VAT account.
• KSeF from 2026 — mandatory e-invoicing means an implementation or software cost (though the Ministry of Finance provides a free tool). We cover this in our separate guide to KSeF.
• Audit of financial statements — mandatory only once at least two of three thresholds are exceeded (50 employees / PLN 33 million total assets / PLN 66 million revenue), so it does not affect small businesses — but it is worth knowing the threshold.
• Changing the address afterwards — if you choose the address badly, correcting it in the KRS means extra fees and time.

Sole trader or Sp. z o.o. — when each pays off

A simplified picture of three typical situations (without ZUS reliefs, i.e. the “steady-state” cost after 30 months):

Scenario 1 — solo, income around PLN 150 000 a year. A sole trader usually wins. Full ZUS plus the health contribution is the main cost, and with low business costs the lump sum or flat tax can work well. A company adds full accounting and double taxation without yet delivering an advantage.

Scenario 2 — income around PLN 500 000 a year. The turning point. A Sp. z o.o. with 9% CIT and no ZUS for board members (of a multi-shareholder company) starts to overtake a sole trader on the scale or flat tax, despite more expensive accounting — especially where profit is reinvested rather than distributed.

Scenario 3 — a team, income around PLN 2 000 000 a year. A Sp. z o.o. (often with Estonian CIT) usually wins clearly — at this level the saving on contributions and tax outweighs all the fixed costs.

Rule of thumb: the break-even point for a Sp. z o.o. usually sits above roughly PLN 200 000 of annual income — but two factors move it: whether profit is distributed or reinvested, and whether full ZUS can be avoided through a multi-shareholder structure.

An example of annual fixed costs — a small Sp. z o.o.

For an active but small Sp. z o.o. (two shareholders, no full-time team), the fixed costs independent of income tax:

On top of that comes income tax (CIT) depending on the result and — if the structure requires it — ZUS and the health contribution for the shareholder. For a one-person sole trader business the equivalent fixed costs (excluding ZUS) are lower: cheaper accounting, and no obligation to keep full accounting records.

Frequently asked questions (FAQ)

How much is full ZUS in 2026? Social contributions come to PLN 1 926.76 a month (with the sickness contribution) or PLN 1 788.29 without it. The health contribution is calculated separately and added to that amount.

Did the health contribution fall in 2026? No. The reform reducing the health contribution was vetoed in May 2025 and did not enter into force. The existing rules apply — 9% of income under the scale, 4.9% under the flat tax, fixed amounts under the lump sum — and the minimum contribution rose (the base returned to 100% of the minimum wage), to PLN 432.54 under the scale and the flat tax.

How much does accounting cost for a Sp. z o.o.? Full accounting for a small company is usually PLN 700–1 500 a month. A sole trader on KPiR or the lump sum is cheaper — PLN 200–600 a month.

From what income does a Sp. z o.o. pay off instead of a sole trader? Usually above roughly PLN 200 000 of annual income, mainly thanks to 9% CIT and the ability to avoid ZUS through a multi-shareholder structure. The boundary moves depending on whether you distribute or reinvest the profit.

As a new entrepreneur, will I pay full ZUS straight away? No. For the first 6 months Relief for a start applies (the health contribution only), and for the following 24 months preferential ZUS (PLN 456.18 in social contributions). Full ZUS begins only after that period.

What is the VAT exemption threshold in 2026? PLN 240 000 — up from PLN 200 000. Some activities (advisory and legal services among them) are nevertheless subject to VAT from the first złoty regardless of turnover.

What does hiring an employee really cost? On top of gross pay you must add around 20.5% in employer contributions plus a minimum 1.5% for PPK. A post paying PLN 6 000 gross really costs the business over PLN 7 200.

Is a virtual office a real saving? Yes. Instead of tens of thousands of złoty a year for an office lease, a registered address with correspondence handling costs PLN 720–1 800 a year in the standard segment. We compare the formats in a separate guide.

Next steps

When planning your company’s 2026 budget, work through four decisions in this order:

1. Legal form — a sole trader to begin with at lower income levels, a Sp. z o.o. at higher ones or where profit is reinvested.
2. Tax regime — match the scale, flat tax or lump sum to your cost and income structure; for a company, consider Estonian CIT.
3. Use the ZUS reliefs — plan the first 30 months so as to take full advantage of Relief for a start and preferential ZUS.
4. Choose the address deliberately — a virtual office is the lowest real fixed cost; compare prices on the same billing basis.

At Henry Estates we provide a prestigious registered address with full correspondence handling — one of the few fixed costs you can reduce without compromising either image or registration security. We serve clients in five languages.
